Abstract

Background and objectives: Anterior cruciate ligament reconstruction is one of the most common knee operations. The graft fixation ways differ from suspensory fixation methods (Endobutton) to aperture fixation (Interference screws). The use of a hamstring tendon autograft has become a common choice among orthopedic surgeons because of less donor site problem. The aim of this study is to compare the functional outcome between suspensory fixation and aperture fixation of arthroscopic anterior cruciate ligament reconstruction.

Methods: Arthroscopic autogenous hamstring anterior cruciate ligament reconstruction was performed for forty-one patients who were divided into two groups, with a minimum of six months follow-up evaluation. The suspensory fixation group underwent endobutton fixation on the femoral side and interference screw on tibial side. The aperture fixation group underwent interference screw fixation at both femoral and tibial tunnels. Both groups were assessed and their functional outcomes were compared before surgery, at three months and six months by using Lysholm knee score.

Results: There was significant improvement in functional outcome in both groups, at six months of follow-up, the Lysholm score in endobutton group improved from 77.2 to 93.2 and in interference screw group from 71.5 to 89. The endobutton group had better functional outcome when compared to interference screw group.

Conclusions: The endobutton fixation provided better functional outcome at the end of six months when comparing the result. We recommend larger population and longer periods of follow-up.
